The new Ve2.1S STM32 OLED1.3" soldering station controller for JBC/T12 - pump control/electromagnetic valve

  • Price: $27.90 (Set 2)

A new version of the Ve2.1S STM32 with OLED1.3 controller has been released. I decided to find out what the "beast" and for one to collect his brother a soldering station.
What came out of it under KAT-om (a lot of text and photos - traffic)

В магазинах торгующих продукцией KSGER (как на Али, так и на Тао), уже примерно второй месяц, есть в продаже новый контроллер паяльной станции Ve2.1S STM32 OLED1.3.
Looked at him in terms of buying. I wanted to know what Chinese inventors-rationalizers had in there. And then my brother, aka leha_marader,asked him to collect a soldering station. And as if hearing our desires, the store itself offered to take this controller for review. To say that I decided to take or not to take for a long time is to say nothing. The controller was immediately bought for a symbolic $2 and after 3 weeks was delivered by courier to the home address.
The parcel is an unassuming white mail bag with postal information

It has a cardboard box with the KSGER logo and the kit number

Box sizes 17 x9 x11cm

Weight 218grams

Inside the kit itself

Packed all very well, the components are tightly fixed with crumpled paper and "puvel"
So, what came:

Ve2.1S STM32 OLED1.3 and 2 plume with BP and GX12-5 connector connector
- HAKKO FX-9501 soldering stick
GX12-5 connector
- and as a bonus from the store - soldering sting KSGER T12-BL

Let's take a closer look at the components that have arrived in more detail.

Let's start with the Ve2.1S STM32 OLED1.3 controller board

The fee has sizes of 62 x 30mm

2mm wider than v2.1S
The installation is two-way.
On one side are: controller, EEPROM, voltage stabilization chains and power part, as well as connectors.
On the back are a OLED_1.3" display and an encoder.

Controller board in detail
Controller's concept

Installation fee

The heart of the board is the controller U1
Stabilized power for the microcontroller and its strapping provides IMS U2 in the SOT-223 case, output voltage of 3.3 volts
The amplification of the signal from the heat vapor of the soldering sting provides the U3 operating amplifier
EEPROM U4 is used to store PID ratios
The power part includes:
is a soldering control channel: MOSFET 1 and the transistor in control of it, the
- Pump/electromagnetic valve engine control channel: MOSFET

To update the firmware on the circuit board, the SWD connector contacts, its C-D-G-V wiring, Clock, Data, GND, z3.3V.
An OLED display with a diagonal of 1.3 is used to display the information"
An encoder is used to control the controller.
The quality of the rations is good, the SMD elements are arranged fairly smoothly, but in places of encoder rations and display there is not laundered flux.

Connection scheme


The Ve2.1S payer board supports JBC and T12 soldering stings.
When using JBC soldering stings, you need to cut the print track between contacts

If after that there is a need to use soldering sting t12 you need to seal the jumper.

The V2.1S payer has the ability to connect both the pump engine and the electromagnetic valve
.
The new Ve2.1S board has the ability to control either the pump engine (no changes to the board need to be made), or to control the electromagnetic valve (to make changes on the board according to the picture)

In this variant, an electromagnetic valve with a power voltage of 24B is connected to the PUMP connector.

Also complete with a board there are 2 plumes

one is used to connect the soldering connector to the backboard, the other to connect the board to the power supply.

After analyzing the concept, we can assume that this fee is a further development or modification of the v2.1S board.
Identified differences in circuitry:
After the U2 stabilizer, there is no D2 protective stabilizator on 3.3V and an electrolytic capacitor C3 at 100mF'6V;
Instead of a resistive R11 assembly on 4.7kM, separate R2, R6 resistors with the same denomination are installed;
- The board is diluted with a cascade of pump engine control/electromagnetic valve 3, D3, R14, R15;
It is possible to use JBC and T12 soldering stings.

Now consider the pen of the soldering iron HAKKO FX-9501

The unmarked pen, no HAKKO FX-9501, no KSGER stickers. Naturally not original.
The casting is high-quality, over-layered and not. The black rubber cuff is quite elastic.
The handle is carefully assembled, the SW200 position sensor and the NTC termistor (in the shrink) have already been crucified

The swing is standard:
- blue wire, SW200 position sensor
- white wire, NTC termistor
- green wire, grounding sting and general position sensor
- black wire, minus the power sting T12 and and common for the thermostor
- red wire, plus power sting T12
In the GX12-5 connector, the undersized wires are not insulated, which is bad, because the connector itself is metal and there is a chance to get a CK

The wire from the pen of the solder to the GX12-5 connector is silicone, heat-resistant, soft enough. If you compare with what I looked at in the previous review, this one is more elastic. Looks like the one I buy on TaoWao..
Long wires 112cm.

5mm diameter

The wire temperature of 350 degrees Celsius withstood without consequences, only the gloss disappeared at the point of contact with the heated sting

The sting in the handle is fixed well, but still cranks along the axis.
The pros and cons of this pen are well known, I think it makes no sense to repeat.

I will not consider the bonus sting of KSGER T12-BL. There are no clear criteria for determining its quality, everything is quite subjective. Someone likes such stings, someone from them is not happy.

To deal with the work of the new controller decided to collect on its basis a full-fledged soldering station (more on the text of PS).

To assemble ps I will need another body and a power supply.

For this PS was bought a kit for assembling a case of dural profile of a long 130mm black color with a silver front panel. At the moment there is no 130mm case on sale, there is 120, 150 and 180mm. The price at the time of purchase was 66 yuan ,whichis equivalent to $10.
The set includes:
2 segments of the 130 x88 x19 P-shaped durallumini profile
- front panel with tinted glass (glass is not usually pasted, the photo is already pasted by me)
- rear panel with a hole to install the 3v1 network pad
- fasteners: 4pc. M3 with a head and 4pc. M3 with decorative head under hexagonal

Whatever repeats, in detail describe the body and its refinement will not be, who are interested can read here. The only difference: in the last review, the case was bought on components in different stores, and in this case I bought a complete set.

In the same store was bought a network pad 3v1. The price at the time of purchase was 3.5 euros, which is equivalent to $0.53.

The pad is the most common, with a fuse and a power switch, to describe in detail I think there is no sense. The only thing I had to do with it was replace the 5A fuse with 1A.

Also, in the same store was bought a power supply on 24B 4A. This power supply is specially designed for use in duraluminium enclosures with a section of 88x38mm (photo from the store)


The cost of this BP in the store is 39, which is equivalent to $5.92.
Claimed characteristics:
- output voltage: 24B
- output: 4A
Power: 96W
Size 83 x83mm.

Power supply board in detail
The power supply is assembled according to the classic reverse-moving pulse scheme based on the SHIM controller with an external transistor.
The SHIM controller (IC3) is used by the FBI12.

).
The printed board is two-way, but all radio elements are located on the top side of the board and tight enough



I will not draw the concept of this BP, but I will consider the basic cascades and elements:
There is a fuse (FS1) on 3A at the entrance

in the future it is possible to replace the jumper, because the network pad already has one fuse and access to it, to replace, is much more convenient
- termistor (NR1)

- Varistor (VR1)

- input-cancelling filter (L3)

- the filter output installed X2 capacitor 0.047mkFx275V

is a high-voltage diode bridge (D9-D12) at 800B and 8A

There are seating seats on the board to install discrete SMD diodes

- The smoothing capacitive filter consists of two capacitors (C17, C18) 22mkFx400V included in parallel

The total capacity of 44mk, for the stated capacity of 96W is not enough.
For a soldering iron with a T12 stinger with a capacity of 70W in principle enough, especially since the peak power is used only at the initial heating of the soldering sting.
If necessary, you can replace the capacitors of greater capacity, the seats allow.
- N-channel MOSFET (N1) power transistor at 650B and 10A, located on a radiator

- near the radiator is a current resistor (R27) 0.18Om 2W
- A pulse transformer is similar in size to laptops used in pulsed BP.

Topology of the circuit board allows the installation of pulse transformers of other sizes

- high-voltage winding snr with RCD supply: diodes (D7, D8) included in parallel, high voltage capacitor (C10) 10nFx630V, resistors (R13-R16) 200kOm included in parallel



- diode assembly is shunted by the R1C2 chain

- Two electrolytic capacitors (C3, C4) at 680mkFx35V are installed behind the diode assembly

- then we have a two-wet throttle (L2)

- at the output of THE BP installed another electrolytic capacitor (C7) 47mkFx50V, it is shunted ceramics (C5) and load resistor (R3) 10 Om

- the voltage stabilisation chain is made in a classic scheme using IMS (IC1)

and optopaths (IC2)

- between the high-voltage and low-voltage parts of the BP installed inter-barrel capacitor (C13) 1.0nF, unlike the "people's" BP, correct, with the characteristic Y1

External inspection of BP left positive impressions - collected qualitatively, ration neat, flux laundered.


Since the case, the 3v1 network pad and the power supply were bought in one store, the delivery in China to the warehouse of the carrier Meest China they have in common, it amounted to 8,800, which is equivalent to $1.21.

The assembly process is quite simple and has no features. I described it in detail in my review.
In a nutshell, then:
- first to the bp board, keeping the polarity we nail the wire going to the board of the controller
- screw the back wall in the bottom half of the case, insert the network pad 3v1
- insert a BP into the guide enclosures, sing to the network pad wires from the power supply
- Fix on the front with a thermal glue tinted glass
- fix the GX12-5 connector on the front, break the train to the controller board, do not forget to isolate the wires
- fix the controller board on the front with an encoder nut, connect the plume connector to the controller board
- attach the front panel to the bottom half of the front panel
Connect the controller board to the BP
I did it like that.

In this position, it is already possible to connect the power cord and conduct a trial inclusion of PS.
Don't forget about the battery. In principle, it is not necessary to use the CR2032 battery, any lithium on 3B will be suitable. The choice of Chinese engineers is the batteries of CR2032 due to its availability, it is, in most cases, used in laptops to power IMC BIOS.A.
As noted above, the controller board allows the use of both a battery with a connector, and batteries with terminals for locking in the board

I plugged the CR2032 battery into the connector.
By and large, you can use a controller without a battery. In this case, you will lose the readings of the watch on the display. If someone can live without a watch on the PS display, the battery may not connect ;-).

If the PS indicator catches fire during the trial, the PS indicator is visible and the information is visible on it

The case can be closed, the soldering pen can be connected, and further health checks and tuning.

The look at the screen of the new Ve2.1S controller has caused a feeling of light deja vu, somewhere I have already seen it;-)

The information on the screen is exactly the same as that of the v2.1S board. That once again confirms the assumption that the new fee is either a further development or a modification of the board version v2.1S.
If you go to the settings menu, paragraph 19 and see Sys Info, we'll see

HW Version is a version of the board release.
SW Version is a firmware version.

I've never seen a 2.10 version firmware before. My controller originally had 2.09, and when I replaced the display from 0.96" to 1.3" I switched the controller to the firmware of version 2.11. And thanks to the efforts of Kembrik comrade a year ago, we have an extreme firmware from the author 2.12.

During testing of the new timer controller, Ve2.1S determined that its control was exactly the same as the v2.1S version. There are no differences in the settings menu. That is, it is still the same v2.1S controller with a slightly different diluted printed board.

Let us sum up the brief subjective conclusions:
The new fee is a further development or modification of the v2.1S board. I can assume that this is its own development from the store
Its parameters and technical capabilities are similar to the v2.1S board
Added the ability to use JBC soldering stings
Added the ability to connect the pump engine or the electromagnetic valve of the dismantling solder.

During the testing and testing of the PS on the new controller Ve2.1S behaved adequately, no nuances or problems in the work were found.
Can I recommend this fee to anyone?
Probably yes. For those who are going to get a dismantling solder with a tin pump or apply JBC soldering stings, this fee will suit more than. For the rest, the choice of Ve2.1S or v2.1S controller board is not fundamental, soldering stations will work the same way based on them.

As always, thank you all for your attention, I look forward to constructive criticism and comments.

P.S. Reminds me that I have on Google disk lined up all the firmware I know for at soldering stations, hairdryer and combo 2v1. And in the "STM32_T12 and Fen Combo_additional materials" are known to me schemes of soldering stations, BP, as well as instructions on setting up and managing the soldering station v2.0-2.1S and hairdryer.

A new version of the Ve2.1S STM32 with OLED1.3 controller has been released.
Get back on the ground. This controller came out last year!!! I already in May 2017 ordered a station with such a controller. Only the pads were not boiled, only holes on the board.

the ability to connect JBC
Yes I saw in the review. but I haven't seen any confirmation of working with them.
And most likely how you wrote it correctly
That is, it is still the same v2.1S controller with a slightly different diluted printed board.
That's marketing and nothing more. For I conclude that those who have the old version can not change. It doesn't make sense. It turns out they did, "facelifting" and gave for a new model. By the way, I understand that yours without the Russian language?
With a connector to connect the pomp?
Holes on the board. The connector should be nailed by itself.

avatar

This, in this version as in the article - weak, you can certainly increase the electricity on the entrance. That's what I'm going to do. BUT on the other hand, the same JBC stings as T12, consume the maximum power from BP only at the moment of initial heating.
and the one I know on the link, but the price tag is not humane. But this is because of the density of the installation and the desire to shove with small dimensions of the powerful BP.

Oh, come on... how do they differ from T12? Or they have a different type of cartridge... the power is different is understandable... And that's it, the princes of control are the same, so this controller will cope... But there's no bp, you need more powerful.

"First of all, is it a sting cartridge?" like T12 right?
- secondly, who prevents you from buying the original T12 stinger?
" in the third, you can't argue with the smaller size and power of the C245... gives a head start.
"And finally, this controller doesn't care what to control, I plugged in the GOOT RX-80HRT-3C stinger, which had the 4th output (1-2 heater, 3-4 TP sensor) combined the findings consistently and connected it with the BC3 profile... everything was perfectly calibrated and solded like the original T12.
Conclusion: cartridges if they are normal and not frank... but, powerful cartridges work equally well even better on the example of C245 ;)

Gentlemen, and there is someone's experience or link to the info/method of how to set up such a controller on THE LED (the settings are already different from the older versions, the page has a description) by temperature. At 200 on the sting 230, at 350 - 340.

All the more strange, here is a completely different controller, "people'" is discussed in other branches, and on the case, your controller is not possible to adjust that he did not lie, even if you will achieve, believe me ... It won't last long.
Use as it is and do not steam:

Already abandoned this direction as unpromising. He began to write his own. I didn't use any third-party libraries at all. All your own. I have the frequency of updating the display 85Hz, the next display does not have time, the Chinese can see how the menu is drawn. I have ANPROM read for 30ms (again the standard limit), the Chinese have 1 sec. The size of the firmware is still 12KB :). The Chinese have 75KB. It will be Russian. You can make a sea of your own settings. Switching the same encoder. Made compatibility with Chinese settings, they will not fly off when rolling my firmware.

Guys, can someone (if not difficult) measure on the front of the station 6 mm (such as in this review) the size of the recess (width and height) where the protective glass is inserted, as well as the width and height of the cutout (window) for the visible part of the screen? I want to figure out in advance if I can insert a 1.54 inch screen.

Hello.
Replaced on the ve2.1S STM32 OLED1.3" soldering station with OLED1.54" with white font. Stood in the back of the aluminium body KSGER (the front panel is native thin aluminum), only had to bite the clippers gently to bite off the bottom of the display board. The only thing it is not as bright as OLED1.3" installed by the seller, may burn out less will.

it is shunted ceramics (C5) and load resistor (R3) 10 Om
And it seems to me that on the shunt 3301 markings. If it's 10 OM on the output of 24B, it's almost sting resistance, and the power is 57 watt...

Here's a working circuit connecting JBC's sting:

BP needs at least 150 honest watts, I have 180.
With this connection, you can easily use the t12 sting without closing the jumper on the board, and unlocking if you need to again sting JBC. Simply in the plug on the pad handle t12 close the contact going on the thermopa with the contact "plus" (green and red in the picture). Thus, when the handle is connected t12 jumper machine closes, and when connected jbc open.
+
avatar
+1
Also JBC sting can connect ala T12, that is, thermopara and heater consistently:

With this connection, the sting works "softer", that is, there is no overheating which is sometimes observed if you connect as described above, with a separate contact on the thermopa. Overheating is manifested when, for example, exposed 350 degrees, and on the regret of another 248, for example, the controller gives a pulse to heat, and before the next iteration of the temperature check the sting manages to heat up to 390 of this pulse, here they are quickly heated, even the firmware behind them does not keep up. But it's a pleasure to be sold out. It is necessary to increase the frequency of iterations of control and temperature control in the firmware.

Hello world!

I would like to ask the useers both T12 and C245-C210. In comparison Hakko and JBC what difference does it make? Pros and cons?

According to the JBC stinging scheme, the handle has vibration and temperature sensors, and the original handle has them? And how many wires are there really going out to the outside connector?
+
avatar
+1
There are no sensors in the JBC handle, there are three wires: the output of the thermopa, one heater output and the general connection point of the heater and the thermopara. The handle itself connects to the stand, and from the stand goes another cable 5 wires on the controller. A temperature sensor is needed to determine the temperature of a cold sleeper. I don't know why it's necessary, apparently to correct the temperature when working in the cold or something, but without it everything works quietly. The controller has the option to expose instead of the use of the stm32 sensor embedded in the handle, which I did (Cold end adj) put "cpu" instead of "ntc" in mode). The vibration sensor is needed for the controller to understand when to enter the stand-off or sleep mode, it can be a mercury sensor, a sensor with balls, magnetic hercon, just closing contacts, a button, etc... In JBC, this is designed so that when we put the handle in the stand, the aluminum part of the handle case connected to the ground is closed with an iron base of the notch to install the handle, and to this very base just and the wire of the definition of the mode is, in fact it is our wire that in T12 goes to the vibration sensor. The controller itself has several modes of behavior selection for this conclusion. I have a choice of SWITCH, that is, type of contact closure, switch. The entrance to the standbay mode is set for 3 seconds and the temperature of this mode is 100 degrees. When I lift the handle to the soldering solder, warm up to the working temperature in a couple of seconds, just as I bring the sting to the ration area. As soon as I put the pen in place passes 3 seconds and the soldering iron again goes to the standbay. The sting once again is not warmed by high temperatures, which is good. And after 20 minutes in general goes to sleep, that is, cools to room temperature. The controller is very versatile, has many settings for different options for the implementation of stands, pens, etc.
In comparison in t12 and jbc I will say that the handle jbc is more convenient than the standard fishing rod and black blue fx9501 from t12. Heating the sting to working temperature at jbc 2-3 seconds against 7-8 seconds at T12. Thin JBC stingers are better than similar T12 cope with the cane-free solder on the boards of phones in heat-intensive places (earth conclusions of capacitors, force throttles, massive landfills). Large stings, such as the t12-k axe (jbc analogue t245-039 and 939), fall about the same, the jbc gain is that heated in a couple of seconds. There will be other stings, I will write here.

Тонкие жала JBC лучше чем аналогичные Т12 справляются с бессвинцовым припоем на платах телефонов в теплоемких местах 

I'd be surprised if it was on the back...
T12 has a sting of 70W. JBC - 150W
and heating time because of less

But there is one caveat, to power JBC stings need a BP for 150W, "people's" on 24B and 4A will not pull

First, thank you very much for your research! Inspired by the comments, he also assembled a station based on stm32's new version of 2019 for JBC's sting. The handle, of course, is cool, but about the sting I can not say the same :(

Warming up is almost instantaneous, it is yes, but the temperature when heated slips the set degrees to 50, and then slowly falls to the set. The reaction to the touch of the warmed solder to the massive landfills is very weak, the station thinks about 2 seconds before adding power. At the same time, the power increases by only a few%. Naturally, melting begins in 5 seconds. T12 in this regard is just a "meteor"!
And the reaction to the stand is kind of strange. It works once out of five! At the same time can squeal as six times, and only a couple of times. In general, the feeling of some kind of flaw.
I changed to version 2.12, nothing has changed.

Ручка, конечно, классная, а вот про жала не могу сказать того же самого :(

И реакция на подставку какая-то странная. Срабатывает один раз из пяти!

- is the pen ready-made or collected?
What kind of sensor is in the handle? Mercury or ball
What kind of stand, how is the sensor oriented in space?
- in the settings of going to sleep (01. Standby) what option is included? I've got a Switch

It's all about JBC's sting. The stand is homemade on the principle of the original: the handle closes the wire, going to the station sensor, on the ground. There are no sensors in the handle. In settings 01. Standby is also on display by SWITCH. Interestingly, if you put the time STANDBY in 10sec, the stand begins to behave adequately, goes to duty as it should be through 10sec, pre-guaranteed squeaking (one long, three short). All problems are manifested at standby time in minutes.
Along the way, the question: do not know, PIDs to put in the firmware nowhere?

JBC sting needs to be soaked ONLY VAC
I don't agree with that. The shape of the voltage does not affect the thermal characteristics of the construct! If you soak up the sting from the 15V parking lot, the controller perfectly normally works out the "trajectory" of heating for 5-7sec. But it is not very "delicious", all the charm of pity is lost ...
I'll try to look at other types of stings in the settings, maybe they'll be better off.

It would be interesting to listen to the experience of working with the stings of alienbody...

Don't go to the steppe, you think JBC chip in 2 seconds to warm up. The chip sting JBC support temperature of 1 degree regardless of the conditions. The shape of the voltage has a very strong effect on the sensor temperature readings.

Well, keeping the temperature is just the controller. No, if, of course, to assume that the controller is quite a curve algorithm, then some correlation from the voltage, perhaps, will be. I don't really need the heating speed, I want a quick reaction to the temperature change of the tip (for example, when touching the landfill). And here at the Chinese JBC quite seams! Experiment: put the sting temperature 150 degrees and dip in a glass of water. It's only turning on in about two seconds!!!
What is this? A controller?? Failed location of thermopara? Or low thermal conductivity material? Probably need to buy the original sting and compare.
In the week, perhaps, I will try...

This may depend on the mass and the surface area of the sting to some extent.
But you didn't even indicate which sting the experiments were going on.

It seems obvious that the greater the heat mass of the sting, the slower the reaction of the controller will come.

I have three Chinese stings similar to C245. For all the result is about the same.
On the subject of obviousness: I have a dozen Chinese stings T12 of different form factors. On any of them, the reaction time to the change in the temperature of the tip does not exceed half a second. On my own C245, which judging by the descriptions on the Internet more efficient, more powerful, less oversized, on which people almost without delay melt landfills, the reaction time is about 2 seconds. More incredible than obvious! So I'm trying to figure out what's wrong...

You can finally tell what kind of sting c245 is. Can with links, or as you will be comfortable.

Or at least compare the mass of the c245 and T12 sting. Preferably only the part near the tip of the sting, where there is a heating element.

at which people almost without delay melt the landfills, the reaction time is about 2 seconds.
See, in the red part of the sting accumulates heat:



And until a significant part of this heat goes into the board/polygon (or into the water) the controller does not notice a decrease in temperature.
And in the Chinese stings T12 there is no such "heat storage" (well almost), the active part of the sting is easier, so faster gives heat until the controller detects a drop in temperature and begins to react to it. Therefore, with T12 stings the reaction time of the controller and less. That's probably true.
(this is an explanation "on your fingers")

But this higher inertia of the controller should not be adversely affected by the ration process itself.

So these reviews are probably based on the application of the original sting. I have the original JBC and for a while were the original Hakko (now only Chinese). IMHO, the quality of JBC's performance is a marked win. So I decided to completely switch to JBC and assemble UniSolder.

The photo shows that the active part of the sting at c245 looks more massive than that of T12 (BCF1, what?).
So it accumulates more heat than T12, which is pictured.
But here the mass is more important, and it is not easy to define it from the photo.

P.S. Thermal conductivity of materials, of course, is also important. It's not even up for discussion.

Had the opportunity to work on Ersa, so there is such a landfill melts in about 2-3 seconds sting similar to T12-Sun3. However, the temperature for the landfills exposed 330 degrees. Now on T12-K "axe" such a test site in five seconds comes.

Ujos! EPSN-40 with a copper sting f5mm melts it twice as fast.
Is this a landfill? It's not even a two-way coat.
Judging by the fact that the temperature of the sting on the station scoreboard does NOT fall then the heat selection from the tip of the sting almost does not go.
Heat is not pumped into the tip of the sting.

I'll answer about my experience. I have the sting c245 axes 039 and 939, curved needle 034, needle 030, hoof 102. So the unsatisfactory behavior stings as Sdoro manifests only in axes. Thin stings (030,034) fall significantly better than the same type of T12. Especially noticeable on 030 sting in comparison with t12-bl. Sting 030 though thinner, but does not stick to the cmd components on warm-intensive tracks, as t12-bl, on which it is impossible to work at all, can just marry what or something.
The sting of 102 in ration is not as much better than the T12-BCF2 as the previous ones, but also noticeable. At the same time, my BCF2 is a bit bad, apparently the Chinese fuck understand what metal in the coating used, and hence the use of the sting 102 is more pleasant.
But the axes 039 and 939 pumped. They look exactly the same, although according to jbc descriptions they should have a slightly different shape, sharpening angle and so on, but that's not the point. The t12 is better, it has faster responsiveness at the first touch. JBC's axe after touching the ration place seems to be thought out for a while. I want to carefully dismantle the tip from one of the axes jbc-x of their own and press the copper tip (also a hatchet) and compare. If the situation improves, it's the materials of the Chinese sting. If not, I'll dig towards the controller and power from VAC.
I have a second JBC pen, so I'm still thinking on the arduinka to assemble a station powered by a trance and see how the power from VAC will affect the ration with the same stings.

I think the situation will improve.
It seems that the blade of the "axe" has insufficient thermal conductivity. It is also relatively thin and long, so it can be a bottleneck for heat flow, especially if it has little copper. But the Chinese copper is not enough.

Do it right away, don't waste your time on reworking the sting.
There will be time to throw a couple of rollers as the controller behaves with the power of VAC and VDC, this will never be seen anywhere else.

The video is likely warming up the sting with 0.
At the same time, even the T-12 is pumped 82-86 w.
But when melting 50g solder when immersing the sting in a solder on a solder at 5-6mm or landfill (where the dive 1-2mm) in the sting is pumped only 25-30v.
The thicker the stinger and the deeper the dive, the more power it gives to solder or water.
In the photo, the D-4 stinger is fixed the maximum consumption at the time of melting the solder mass.
25 w it consumes when installing 300 C and immersing in solder on 5-6mm (a jar ceramic pad from a single-armed crane with a deepening of 5mm).
And 32W it consumes when installing 330C.

Strange as you look, the handle on the stand in hibernation begins from 150 to 350.

Rejoice, the original T12 stinger at 75 W.

But when melting 50g solder when immersing the sting in a solder on a solder at 5-6mm or landfill (where the dive 1-2mm) in the sting is pumped only 25-30v.
So on any blowtorch, during the rations never pumped full power, because you have a sting does not cool down to 0 at the time of touching the landfill or solder.

When I touch any landfill, the temperature is 2-3 degrees, the controller has 30 to 40 W to restore the specified temperature.

Never noticed that the controller to maintain a temperature of 2-3 degrees pumped 130 w into the sting.

You have "forgotten" at least 3 things.
IBB efficiency, UPS capacitors charge at FIRST launch and consumption of the controller with an indicator of 3V.
Or they didn't.
A total of 72w stinger, 3v controller 11w for the loss of UPS and the charge of capacitors.

If the landfill is not pumped full power means the designers missed.

I have a similar BP. Bought in China on tao began to whistle trance. It's a shame, man. And the station almost did not have time to use, and already whistling appeared. Maybe who knows if this trance can be resuscitated? I haven't taken it apart yet, but it looks like a ferrit with a crack. I do not imagine how this could happen, given that initially the squeak was not and the station no one dropped ) By the way on Ali now sell stations with a little other BP for aluminum casings, supposedly updated version with a more stable maintenance of the temperature of the sting.

To compare the work of JBC's AC sting, the arduino-based controller, the thermopara amplifier on lm358, the power transformer 26V, the cymister control
optron, the removal of temperature occurs at the moment of crossing the AC zero
Transformer.
GreatScott www.instructables.com/id/DIY-Arduino-Soldering-Station/.
Beyond the lack of max6675 (as in the author) the reading of the temperature readings from the thermopara I made on lm358, instead of oled applied lcd 16 x2, the firmware its own. Added signal processing from the stand sensor to have a sleep mode.
Compared a bit of the work of using this circuit on a variable toe and controller
stm32 oled V2.1S using DC 24V. On the AC works
about 15% better, but no more. Maybe because it's a trance on 26th, but on
The simistor should fall at least 2 volts, so that in the end the conditions are approximately equal.
Control so far without APS, stupidly when passing the accommising zero (100 times per sec.)
triggers an interruption in which if the thermopara readings are less than the variable set
resistor the temperature value, then open the systor and half-wave heats the sting.
Temperatures jump at around 3 degrees at room temperature and off
I'll wait for max6675 c ali and see how it goes.
In the plans instead of a resistor stick a couple of three buttons or encoder to control, in the firmware
add a menu of all sorts to change and save settings, calibration, etc., instead of a simistor
Use a pair of mosfets, screw up the PID and control the Shim signal.
Everything is collected on the nozzles on the layout board, without the case, with a bunch of wires, so the photo will not be yet.

lm358 probably in this scheme on stable will be, max6675 do not think that the accuracy of temperature will change in JBC thermopar not K-type. Take the ready-made version for JBC from the Chinese, a classic scheme on stm32.

Here's another version on the classic stm32 T12 ennobled enclosure, on display the same "parrots."

The station came, for 8 days from the ketaya. Having a sad experience on the burnout of such a display 0.96" decided not to wait, and immediately count the resistance to the current less than the estimated date 3 times. For on date the formula is given for max. Current. The display in this situation burns out much faster.
On the amplifier, as it turned out, this resistor stood exactly according to the formula of the date on display. The display burned out to the indecency for a couple of years. Now there's like a 910k-com-disconnection display display.
Screen from date stitch on 1.3" display:

We have Vcc 7.8v.
Based on the formula, it turns out to be R1 (7.8-2.5)/12.5uA/424kOm.
A 510kOm was installed on the display board. Good, but not enough. Let's reduce the current by 3 times:
12.5/3=4.166uA. This is the current on which we will count the resistance of R1.
R1 (7.8-2.5)/4.166uA/1.2M. I bet 1.5M.
Without a light filter, the difference in brightness did not notice when the station assembled IMHO became a little dimmer display. Not a TV staring at it from a few meters away... He's going to roll.
The resistor needed is on the display board. Find it easy -- he's one of such big denominations. In my copy in general there was one resistor assembly on 4.7kOm and this resistor on 510km.

Repaired an LED lamp at work. I take for the fee of LEDs with one hand, a stinging solder on the output of the LED ... You can see how almost all LEDs begin to light up. Tester at recess, a probe in the hand, the second on the iron soldering iron. Shows about 40 volts. The sockets at work are grounded, at least that's how it should be.
Houses about 8 volts, sockets are ungrounded. The LED lamp is not available for inspection...
Is that even normal?

Dear vulkan35 here repeatedly hinted that it is necessary to nourish the JBC-stinger VAC, so I collected a scheme on the ardoine and powered heater from the transformer. As a result, the resulting soldering station showed an almost imperceptible increase in quality, probably a maximum of 15%. My axe stings were still as brooding as Sdoro's,but it was somehow more explicit than I had expressed it.
I was not satisfied with it, or rather it was a pity became the forces and funds (about one and a half thousand rubles) spent on the above-described station with a variable current. Well and I decided to improve one of the sting jbc.

There were 5 stings: needle 030, isyla needle 034, hoof 102, knife-shaped 039 and 939. The latter were completely the same, although the JBC catalog should be slightly different (the angle of sharpening at least), and because they were claims one of these two put into expense.

Made a saw along the sting along the entire length of the tip with a slumber, neatly small pliers removed the stinger, in the hand just remained a kind of blank. Then took one of the available copper stings for my old hatch, shortened, planted on the hull blanks. The most problematic is to fix it, because the diameter of the blank in the place where you need to plant a stinger 3.5 mm, and the diameter of the hole in the existing stings of the 900 series ranged from 4 to 4.5 mm. Selected was a naturally stinger with a smaller diameter, and luckily it turned out to be a stinger-like axe. Gently began to compress the mites for the crimmination of the coaxial cable, once 10 along the entire length constantly turning so that the voltage in the metal was evenly along the entire length.

As a result, I got a stinger with a completely copper tip. Immediately decided to check it in the case, and pleasantly surprised, or rather not disappointed as a result, the former problems with thoughtfulness disappeared. As I had previously expected, this indicates a lack of quality of materials on the native Chinese tip. So you can safely change the tips on the problem stings on copper and everything will be the way.
Here's a comparison with 900 stings:

It's fun, with T12 stings such a trick can not turn out ...

Sawed the working part of the tip of the removed Chinese stinger nadfil and in the cut you can see only a thin layer of copper, and a very thick coating with another metal. Metal is magnetized, nickel or something else, I do not know, but the tip is light, it feels easier than if it was entirely copper.
And from here it is clear why the sting behaved so, in the working part of copper is not enough, the thermal conductivity is small, that's the secret.

After a week of operation sting with 245 with a "self-directed" tip I can safely say that it has the full right to life and even more. Previously, when working with desktop and laptop boards on the stainless had to quickly and comfortable to drink heat-intensive elements (or from heat-intensive landfills) to bully the temperature up to 350 degrees, at the usual working temperature at a sting of 300 degrees when the little thing every solder (sometimes 320 put, because the unsaltalled and the boards are different, then when the bust to 370 temper rose).
Now on this regret I put 300 and sold all not paying attention to heat capacity, that is, put and forgot ... It's falling and it's going to be a good time: the conders, the transistors, and the throttles, until I got the point of having to blow the temperature. Probably as if I get original stings, and compare with them ...

The soldering station came from the KSGER store with Tao, bought to order.
A new version of the blue board has been installed


here's a guess, review do or not?
The differences, at first glance, are not significant:
3.3B pulse stabilizer
- Divorced contact areas for pump engine and valve control cascades

Hmm... A Muskovchanin, who connected jbc, claims that the cutter goes to contact, and if it is put out, on the contrary, will tear the track on the OU. To connect JBC, you need to cut the track from the power sting, and the cutter R11 0 Om leave in place.

In reviews on Ali to such a fee complained that there still changed ou to less precision, so never bought this fee on sale, as reviews for the 2018 version already several, and what exactly changes in the version of 2019 no one has yet accurately written. If there is time, please do a review of this station, and then I will continue to sing EPSN-ami for the rest of my life:-)

Tell me, what is the power of JBC stings with 210 and c245?
+

someone here wrote that 130W... c245 has the resistance of the heater about 4 om, according to the law of oma if you count that on 22 volts there will be such power ... I've got 24 feeds

Power c210 60W, c245 130W.

Thanks for the info.
I would like to try a Chinese JBC buy.
They still have both c470 stingers and stations in the collection:
for c210 and from245: link
And for c470: link

Only reviews are not at all on such a station.

Yes, I've seen the reviews.
But your version with a capacity of 75W, i.e. does not reveal danced with245.
And one channel.
And the price turns out that somewhere equally.
"But still, it's not a bad option either.
Although read the comment on the link that gave, and write"Be sure to calibrate!!! With original stings lies 100 degrees plus. Calibration in general is a tinge: when calibrating it is necessary to enter millivolts of thermopapa and when calibrating the heating is disabled - what did the manufacturer think ?"
